PRNU Correction (Pixel Gain Correct)
PRNU (photo response non-uniformity) is a variation between pixels generated by the sensor
under bright conditions. If the line rate is slowed or a long exposure time is set, the dark current in
the sensor may change and the state of the PRNU may change.

1. Specify the user area (User1 ~ User3) to save the gain correction value with
PixelGainCorrectionMode
.
Note:
You cannot perform calibration when
Off
or
Default
is selected.
2. Gain correction data is automatically generated by
PerformPixelGainCalibration
and
saved in the user area specified in step 1.
3. You can check the execution result of gain correction by
PixelGainDetectResult
.
